    Default Opensuse Server with Asus M4A78T-E motherboard RAID 5 configuration

    a very good day to you all,

    this motherboard of Asus M4A78T-E has in the HCL Motherboards the status that everything works out of the box.

    could someone confirm if Open Suse Server works with this onboard raid 5 controler?

    thanks in advance.

    So, here is a hand grenade answer as they say. I have a Gigabyte GA-790A-UD4 main board and a RAID "0" setup on the same chipset SB750 and it works with openSUSE 11.4. I guess I have not had a setup to try RAID 5 before or the same motherboard you have and so it is hard to say if close is good enough to be accurate for you. Basically, if you can select the RAID drive as a bootable in your BIOS setup and/or the drive is recognized when booting from a openSUSE 11.4 LiveCD, your chances are good that it will work. It is as close as I can get to a good answer for you.

    Thank You,

    But even today a 7 drive RAID 5 with 1 TB disks has a 50% chance of a rebuild failure. RAID 5 is reaching the end of its useful life.
    Surely not an answer ... but may I suggest some interesting readings about RAID5 in general: Why RAID 5 stops working in 2009 | ZDNet

    So that is a kind of disheartening story please_try_again. Of course I went for speed when using RAID 0 and dam the data loss. However, a long time ago I decided to just keep more than one copy of my important data. That is not the same as making a backup. Rather, I copy important stuff to more than one hard drive. I still use backups of course, but having more than one copy seems to get past other stupid things I have done before, including bad backups, unforeseen bad disks and reinstalls of ones OS without doing a "recent" backup. Extra Hard Disks can be cheep compared to regaining ones data in many cases.

    Yes, I have to admit.

    Another hand grenade answer here ....

    I had that exact same board (M4A78TE) using Raid - 0 on 11.2 and worked great.
    Desktop- AMD Phenom II X4 810 8GB RAM Radeon HD 4790 openSUSE 11.2 x86_64 KDE 4.3.5
    Laptop - Intel 2.27GHz Core i5 M430 6 GB RAM nVidia GeForce 310M openSUSE 11.3 x86_64 KDE 4.5.2

    thanks for your time and answers.
    raid 5 is still the answer for fast data read and write in a network with multiple users.
    and a way to minimize down time especialy with linux.
    i am going to set up a server for 10 users with this main board and the AMD Phenom II X6 1100T / 3.3 GHz.
    my only doubt is the amount of ram memory 8 or 16 Gb.
    hope it works like a charm.

    thanks again till next time.

    Don't know but it doesn't matter. IMHO, you'll do better to use linux
    mdadm RAID instead, so you won't be using the SB750 fakeraid feature.

    I have a different opinion. RAID 5 used to be good but there are better
    choices now.

    First, if you think you want RAID 5, then use RAID 6. With larger disk
    sizes the risk of a double failure during rebuild starts to be significant.

    Second, with fakeraid, either RAID 5 or 6 imposes a higher CPU load for
    the parity calculations. They're still OK with real hardware controllers
    - Areca, LSI etc.

    Better to use RAID 10 plus hot spares in my opinion. But best to
    benchmark your own workload.

    How much memory depends on what your server is doing. If it's just a
    file server, you don't need as much memory. If you're running
    applications as well, then it depends what you're running. Does each
    user have a working set less than 0.8 GB?

    if i hustle all the info i read today i also think there is a better solution.

    in the first place i wonder if we need that much storage. raid 5 = 4 x 1.5 tb = 4.5 tb and raid 6 = 3 tb.
    that is a very large volume.

    maybe it is better to install linux on a ssd and one 1.5 tb hdd with some kind of backup.

    there are so many discussions about which raid to use.
    and more important where the edge lies where it is a way to never loose data.
    for as far i can see now it would be a raid 61.

    what would be the most wise solution to create performance and storage (max 1 tb) and a backup function?

    maybe freenas with raid 61?
